2006 GMC Yukon and Denali Review
Yukon and Denali offer no changes of note for 2006, awaiting a redesign due during the '06 model year. Yukon and Denali are GMC's versions of the General Motors large SUVs also sold with Chevrolet and Cadillac nameplates. Yukon is an upscale sibling of the Chevrolet Tahoe. The longer Yukon XL is a retrimmed Chevy Suburban. Denali and Denali XL are Yukon's luxury versions. Cadillac's Escalade is the third member of this SUV family.
Yukon XL comes in half-ton 1500 and three-quarter-ton 2500 models. Other Yukons and Denalis are 1500s. All have a rear liftgate with separate-opening glass and seat up to nine. Front bucket seats are standard on Denalis and available for Yukons in place of a 3-person bench. Twin 2nd-row bucket seats are optional to replace a 3-person bench. A 3rd-row bench is standard for Denali, XL SLE, and XL SLT; available for regular-length Yukons and XL SL.
All models have a V8 engine. A 285-hp 4.8-liter is standard in regular-length Yukons, a 295-hp 5.3 is available. The 5.3 is standard on Yukon XL 1500s. A 335-hp 6.0 is standard on Denali and 2500 models, a 325-hp 8.1-liter is optional for the 2500.
All models have an automatic transmission with GM's Tow/Haul mode. Denalis include all-wheel drive without low-range gearing. Yukons offer either rear-wheel drive or GM's Autotrac 4WD that can be left engaged on dry pavement and includes low-range gearing.
All models have antilock 4-wheel disc brakes. GM's Stabilitrak antiskid system is standard for Yukon and Denali models. Front side airbags are standard on Denalis, available elsewhere. Yukons get standard 16-inch wheels or optional 17s. Denalis come with 17-inch wheels or newly available 20-inch chrome wheels.
GM's OnStar assistance is standard on all models. Denalis come with power-adjustable pedals and an automatic climate system with front/rear controls. All are available for Yukons. Optional for SLT and Denali models is an audio/navigation system, which adds a control touch screen.

Competition
Consumer Guide® Automotive places each vehicle into one of 17 classes based on size, price, and market position. Large SUVs are traditionally workhorse 7-plus passenger wagons with brawny chassis, ample towing ability, lots of cargo space, and generally abysmal fuel economy. These vehicles offer towing and payload ratings similar to large pickup trucks.
Our Best Buys include Chevrolet Tahoe, Chevrolet Suburban, and Ford Expedition. Our Recommended picks are GMC Yukon, GMC Denali, and the Toyota Sequoia.

News
Though just redesigned, these GMCs and their Chevrolet relatives are expected to add a hybrid powertrain option for 2008. The result of a GM-DaimlerChrysler-BMW collaboration, this "two-mode" system is said to use twin electric motors and a 300-volt battery pack to assist a 5.3 V8 with GM's Active Fuel Management cylinder-shutoff feature. It allows low-speed driving on either power source, and promises better overall fuel economy than conventional powertrains. Rival Dodge's midsize 2007 Durango SUV offers a similar hybrid option.

Consumer Guide® Road Test Ratings
Acceleration
Always adequate, though 4.8 V8 feels taxed with heavy cargo or towing loads. Automatic transmission a model of smooth, alert shifting. No opportunity to test XL 2500. Maximum towing capacities with largest available engines: 7800 lb for Yukon 1500, 12,000 lb for Yukon XL 2500, 8100 lb for Denali.
| 2WD Yukon, 4.8 V8 | 4WD Yukon XL, 5.3 V8 | Denali | Class Average |

Fuel Economy
In our tests, a Tahoe averaged 12.2 mpg, a Suburban 11.5; both had 4WD and 5.3 V8. Comparable GMCs do the same. Test '04 Denali XL averaged just 9.8 mpg. All engines use regular-grade fuel.

Ride Quality
Base suspension is more controlled and absorbent than the available Autoride system, which is standard for Denalis. No opportunity yet to test Denali with 20-inch wheels. Yukon's available off-road package rides stiffly, so try before buying.

Steering/Handling/Braking
No big SUV handles like a car, but these GMCs are competent for their size. Base suspension outshines Autoride, but steering lacks good feel either way. Credit GM for making the antiskid system standard on all Yukon 1500 and Denali models. Stopping power good, with firm, progressive pedal movement.

Quietness
Wind rush not intrusive. Tire noise audible at highway speeds, but moderate for large SUVs. Full throttle brings on engine roar, but these V8s are smooth runners.

Controls
User friendly, with legible gauges and intuitive controls all placed reasonably close. GM lags Ford and Toyota in not offering side curtain airbags in its big SUVs; charging extra for front side airbags in Yukons is a further demerit. Navigation/audio combo a sensible idea, relatively easy to use. Fabrics, plastics midquality at best even in higher-priced, leather-upholstered Denalis.

Room/Comfort/Driver Seating (front)
Stretch-out space on wide, supportive seats. Drivers have commanding view, but some nearby objects can't be seen, and no obstacle-detection system available. Standard heated seats among Denali comforts.

Room/Comfort (rear)
All models have space aplenty in 2nd row, and Denali includes heated seats. XLs offer adult-size room in 3rd row, but only kids will be happy there in other models. Lower step-in than Ford Expedition and Excursion, but higher than typical minivan; available running boards help. Rear doors' narrow lower openings hamper ingress/egress, especially on regular-length models.

Cargo Room
XLs take fair-size loads behind 3rd-row seat. Regulars have little more than grocery space, but their 50/50 split seat is more versatile than XLs' one-piece bench--and also easier to remove or install.

Value within Class
Yukon and Yukon XL offer fine value and most of the sensible luxury options anyone could want. Denalis mix those basic virtues with more standard power and extra amenities, but not enough of either to warrant their higher prices. So our Recommended label applies to the Yukon versions.

Pricing Key: Retail prices listed with each report are set by the vehicle's
manufacturer. These figures appear on each car's federally mandated window sticker.
Most price lists also include dealer-invoice prices. Dealer-invoice prices are
what the dealer pays the manufacturer for the car and its factory-installed options.
The destination charge is not included in the suggested-retail or dealer-invoice price
and must be added to the cost of the vehicle. Car companies change prices frequently
throughout the year. If the prices published do not match those on the vehicle's
window sticker, the manufacturer has probably altered the price recently.
NA = price note available, NC = no charge.

NHTSA Crash-Test Results
| Test | GMC Yukon/Denali 4-door wagon | GMC Yukon XL/Denali XL 4-door wagon |
| Front Impact, Driver | 5 | 5 |
| Front Impact, Passenger | 5 | 5 |
| Rollover Resistance | 3 | 3 |
The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's
worthiness in front- and side-impact collisions and rates its resistance to
rollovers. Front-impact crash-test numbers indicate the chance of serious injury:
5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Side-impact
crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%;
1 = More than 26%. Rollover resistance numbers indicate the chance for rollover
when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%;
2 = 30-40%; 1 = More than 40%.
